Question 1

Which of the following best describes the process of transduction in sensation?

Accepted Answer

The transformation of physical stimuli from the environment into neural impulses that the brain can process.

Question 2

According to Weber's Law, the just-noticeable difference (JND) between two stimuli is:

Accepted Answer

A function of the magnitude of the original stimulus, expressed as $ \Delta I / I = k $ where $ \Delta I $ is the change in intensity, $ I $ is the original intensity, and $ k $ is a constant.

Question 3

Which scenario best illustrates sensory adaptation?

Accepted Answer

Becoming less aware of the sound of traffic outside your window after living in the city for several months.

Question 4

Signal detection theory is primarily concerned with:

Accepted Answer

The ability to detect a weak stimulus in the presence of uncertainty, considering both hits, misses, false alarms, and correct rejections.

Question 5

Which of the following is an example of an absolute threshold?

Accepted Answer

Detecting a candle flame 30 miles away on a dark, clear night.

Question 6

Gestalt psychology emphasizes which principle?

Accepted Answer

The whole is greater than the sum of its parts.

Question 7

Which Gestalt principle explains why we tend to group objects that are close to each other?

Accepted Answer

Proximity

Question 8

A researcher presents a word for a fraction of a second, followed by a mask, and finds that participants are more likely to respond to related stimuli later. This is an example of:

Accepted Answer

Priming

Question 9

Which of the following best describes the 'figure-ground' principle in perception?

Accepted Answer

Distinguishing an object (figure) from its background (ground).

Question 10

In the context of vision, which cells are responsible for detecting colour and are most concentrated around the fovea?

Accepted Answer

Cones

Question 11

Which pathway in the brain is primarily responsible for processing information about 'where' an object is located?

Accepted Answer

Dorsal pathway

Question 12

Which of the following is NOT a factor that influences a person's ability to detect a weak stimulus according to signal detection theory?

Accepted Answer

The colour of the stimulus

Question 13

Which of the following best illustrates the concept of 'closure' in Gestalt psychology?

Accepted Answer

Perceiving a complete shape even when parts of it are missing.

Question 14

Which statement about rods and cones is correct?

Accepted Answer

Cones are responsible for colour vision and are concentrated in the fovea.

Question 15

A person is able to detect a teaspoon of sugar in a gallon of water half the time. This scenario is an example of:

Accepted Answer

Absolute threshold

Question 16

Which of the following is a drawback of sensory adaptation?

Accepted Answer

It can lead to damage of sensory organs, such as getting used to loud music in headphones.

Question 17

Which of the following best describes the concept of 'priming'?

Accepted Answer

Previous exposure to a stimulus influences response to a later stimulus.

Question 18

According to the doctrine of specific nerve energies, which statement is true?

Accepted Answer

Different sensory modalities are processed by distinct neural pathways.

Question 19

Which of the following is an example of a 'false alarm' in signal detection theory?

Accepted Answer

Reporting a missile when it is absent.

Question 20

Which of the following best explains why we may fail to notice clearly visible events or objects?

Accepted Answer

Attention is directed elsewhere, leading to inattentional blindness.
